Answer:
both zeros are irrational numbers
<u>Step-by-step explanation:</u>
Note: The question would have made more sense if if it was 2/x = x - 1 but I will answer it as written.
Take out the GCF of -4d, which creates
-4d(d^2+7d-1)
Doesn't seem right... tell me if I messed up anybody... if not, there's your answer.
I would say A because if you draw a forumula triangle you and cover the H it would give you that x
f(x) = 4x + 3
That's one-to-one, a linear function that will give a different f(x) for each different x.
For the inverse let's swap x and y and solve for y
x = 4y + 3
x - 3 = 4y
y = (x- 3)/4
That's the inverse,
Answer: (x- 3)/4, second choice
The domain and range of the inverse is all real numbers. It's two lines; I'll leave the graphing to you.
